Ever wonder what country artists do in their off time? Quite a few of them were rocking out to Bruce Springsteen on Wednesday. The rock legend brought his seven-piece E Street Band to Nashville’s Gaylord Entertainment Center, and spotted in the crowd were Collin Raye, John Fogerty, John Prine, Danni Leigh, Wynonna Judd, Billy Dean, the Oak Ridge Boys and Sawyer Brown’s Hobie Hubbard and Jim Scholten. Patty Loveless and Kathy Mattea also were seen singing along with the rocker’s signature anthem, “Born to Run.” During the three-hour show, Springsteen dedicated his song “Mansion on the Hill” to country legend Hank Williams, quipping he borrowed the title from a Williams tune.
